Tightness and leakage (compression and leakage) play an important role in the performance of any system or component. Tightness refers to the condition when a component or connection is completely sealed and no liquid or airborne material can escape. On the other hand, leakage refers to a problem where liquid, gas or air leaks out of the system, which reduces the performance of the component and causes damage.
Appropriate sealing materials are used to ensure tightness, such as rubber gaskets, sealants, or other sealing technologies. Leakage is usually caused by old or poor-quality seals, mechanical damage, excessive pressure, or design defects. Leakage problems can cause system pressure to drop, environmental pollution can occur, and sometimes, safety risks can increase. Therefore, maintaining tightness is very important in the design and maintenance of any component. Ensuring regular inspection and maintenance can reduce leakage and prolong the performance of the system.
